Science and technology daily (reporter Zhang mengran) an engineering paper published by the British magazine Nature recently reported that a robot can jump 30 meters high, more than 100 times its height. It surpasses the design of Jumping Robots and the most powerful high jump creatures reported so far. This achievement may change the way we use high jump robots and show a new level of jumping ability of man-made engineering design.

For decades, engineers have designed jumping machines, often imitating or inspired by organisms. The maximum jumping height of an animal is limited by the work that its muscles can do in a single action. On the contrary, if the design device adopts ratchet or rotating motor that can store energy in repeated action or rotation, the jump height will be much higher.

This time, Eliot huaks, a researcher at the University of California, and his colleagues designed and built a special robot, which is about 30 cm high, weighs 30 grams and can jump 32.9 meters high. It has a rotating motor that multiplies work and has a specially selected spring and rubber band to allow the system to store energy. The research team said that their results have changed the meaning of jumping as a means of movement and how and where jumping is applied.

In the attached news and opinion article, Sara bogbrett, a scientist at Carnegie Mellon University, said that on earth, jumping robots can avoid obstacles that used to be navigated only by flying robots and collect images of the ground below. If Jumping Robots jump on the moon, where the surface gravity is weaker, they may jump to an altitude of 125 meters, so that they can cross a distance of half a kilometer at a time, Or it can be used for topographic exploration and investigation.
